Specification of Letters Patent.

Patented May 13, 1913.

Application filed September 24, 1910. Serial No. 583,678.

To all whom it may concern Be it known that I, ANTON IlANSEN, a citizenof the United States, residing at Greensburg, in the county ofWestmoreland and State of Pennsylvania, have invented a new and usefulImprovement in Valves, of which the following is a specification.

This invention relates to valves and particularly to gate valves and thevalve disks therefor. It has for its primary objects: the provision in avalve of the character specified, of improved interlocking disks ofsimple and inexpensive construction which may be readily assembled andtaken apart and which when placed in locked ope 'ative position, willremain in said position when removed from the valve casing; theprovision of a simple arrangement of interlocking means for the diskswhereby disks, which are duplicates may be utilized; the provision ofimproved means for guiding the disks during movement in the valvecasing; and the provision of a simple and se cure locking means in avalve of the character described wherein provision is made for accurateseating of" the disks. These together with such objects as mayhereinafter appear or are incidental to my invention I attain by meansof a construction illustrated in preferred form in the accompanyingdrawings, wherein Figure 1 is a vertical section through my improvedvalve; Figure 2 is a plan view of one of the disks through which thevalve proper is formed; Figure 3 is a top view of one of the disksshowing the guide lug of the casing arranged within the guide member ofthe disk; Fig. A is a side elevation of a disk nut; and Figure 5 is aplan view of the same.

Referring to the drawing, it will be seen that I employ a valve casing Aof usual form which has an inlet and outlet port and a pair of annularshoulder portions B threaded to receive the seat bushings C which arepreferably composed of a soft metal. The valve D is inserted in theeasing through the usual opening in the upper portion thereof and iscomposed of two valve disks E which interlock and embrace the disk nutM. The disks E are duplicates, each disk comprising a substantially flatbody portion having an outwardly projecting T-head lug F and a rib Gwhich is recessed to receive the T-head lu The cornew and the surface Fof the T-heads are rounded to provide a slight relative rocking motionbetween the disks in order that the disks may take proper seat on thebushings (J. From the :t'oregoing it will be seen that the disks areinterloclmd by relative crosswise movement, and that when sointerlocked, they are held against movement apart on the line of theiraxis, though there is a small amount of relative rocking movement asabove described.

The disk nut M is provided with two feet, M, having flanged bottoms andis held in position between the disks by means of the lugs N-N and O()which engage the flange portions of the feet and by the ribs G whichabut the bottom of the flanges. This arrangement of parts preventsrelative lateral and vertical movement between the disks and the disknut when the disks are locked together. The disks are guided in theopening and closing movement of the valve by means of hook members Jwhich engage ribs A cast on the valve casing A. One such hook, J, isprovided adjacent an edge of a disk and it will be apparent when twodisks are locked with faces toward each other that there will be a hookon each side of the assembled valve engaging a rib A thereby insuringproper guidance of the valve when itis moved. The outer face of eachdisk is provided with an annular insort I preferably composed of softmetal which contacts with the scat bushings C. A recess K is provided oneach disk which is adapted to receive the hook member J of the otherdisk of the valve and permit the proper assembling of the disks.

It will be apparent that a suitable valve stem for operating the valveis threaded into the disk nut M.

By the above described arrangement of parts it will be seen that thedisks may be readily assembled and locked together in operative positionand that when so locked, they will remain in operative position evenafter being removed from the casing. The locking means is simple anddispenses with the provision of any third members, and are of such acharacter that the disks may be exact duplicates of each other; that is,made from the same pattern, thus greatly reducing the cost ofmanufacture and the labor in assembling. At the same time, provision ismade for guiding the disks, for securing proper seating of the disks andfor securing the disk nut in the valve. Other advantages will occur tothose familiar with the art. It will be apparent that if desired, the Thead lugs may be provided on one disk and the recessed ribs on the otherdisk.

Having thus described my invention and illustrated its use, what I claimas new and desire to secure by Letters Patent is the following 1. In adevice of the character described, a pair of disks provided withinterlocking members interfitting relatively loosely to per mit arelative rocking movement and adapted to lock the disks against movementapart on the line of their axis, said members being adapted to lock andbe unlocked by relative movement transverse the axis of the disks.

2. In a device of the character described, a pair of disks provided withfixed locking members formed so as to permit of a relative rockingmovement of the disks and adapted to lock the disks against movementapart on the line of their axis, the said members being locked onrelative movement between the disks transverse their axis.

3. In a device of the character described, a pair of disks provided withlocking members comprising a T-head member, and a member recessed toreceive the T-head, the said members locking the disks against movementapart on the line of their axis and being locked and unlocked byrelative movement of the disks transverse the line of their axis.

4. In a device of the character described, a pair of disks provided withlooking members comprising a pair of T-head members, and a pair ofmembers recessed to receive one of the T-head members, the said memberslocking the disks against movement apart on the line of their axis andbeing locked and unlocked by relative movement of the disks transversethe line of their axis.

5. In a device of the character described, a pair of disks provided withlooking members comprising a pair of T-head members, and a pair ofmembers recessed to receive one of the T-head members, the said memerslocking the disks against movement apart on the line of their axis andbeing locked and unlocked by relative movement of the disks transversethe line of their axis, and the said T-head members having their outersurfaces slightly rounded to permit of relative rocking motion betweenthe disks.

6. In a gate valve, the combination of a casing, a valve seat therein, apair of interlocking disks which are duplicates of each other and amovable element adapted to seat the disks against the valve seat.

7. In a gate valve, the combination of a casing, a valve seat therein, apair of interlocking disks which are duplicates of each other and amovable element adapted to seat the disks against the valve seat, thesaid disks locking against movement apart on the line of their axis.

8. In a gate valve, the combination of a casing, a valve seat therein, apair of in terlocking disks which are duplicates of each other and amovable element adapted to seat the disks against the valve seat, thesaid disks locking against movement apart on the line of their axis, andbeing locked and unlocked by relative movement trans verse the line oftheir axis.

9. In a valve of the character described, the combination of a valvecasing provided with a valve seat, a pair of disksprovided withinterlocking members adapted to lock the disks against movement apart onthe line of their axis, and a movable element adapted to carry the diskswhen they are interlocked and seat them' on the valve seat, the saiddisks being locked and unlocked by relative movement of the diskstransverse their axis, the connection being such as to permit of aslight rocking movement between the disks.
